Framed Signal (Modes 6,7)
Both Master and Slave move directly to the FRAMEDET sub-state on completion of the
4LVLDET training functions. The devices begin executing their internal algorithm to search for the
FSW. As soon as the FSW is detected in the appropriate place in two consecutive frames, the
device moves to the Active1 state. The devices remain in the Active1 state until the MAT expires,
then move to the Active2 state. Received data are available, and the ACTIVE indicator is asserted
in both the Active1 and Active2 states. The only difference between the Active1 and Active2 states
is the status of the MAT.
The EMDP provides a mean for abnormal termination of the activation process. Expiration of the
MAT will cause immediate termination of the activation process. When MAT expires, the EMDP
moves directly to the Deactivated state.
